This is easy - never spend $20k on any equipment unless you are absolutely sure that that is what you want. Unless you print the money or have others do it for you. There are a number of people like that, by the way, they collect money without earning it.
$20k buy great used speakers, it doesn't buy great new speakers, as far as I know, so I would proceed with used after auditioning them. If that is impossible I would do my best to make impossible possible. If it fails - to hell with those speakers, there are others, not a big problem. They are just boxes with parts in them, nothing vital.
